As Tennesseans head to the polls Tuesday, they will have a chance to decide who they want to represent them on all levels.

On this year's ballot are open positions for the U.S. Senate and governor, as well as the state's nine U.S. House seats and 17 state Senate and 99 state House of Representatives seats.

As Tennessee Republicans look to maintain their supermajorities in the state legislature, and hold onto the offices of the governor and Senate, here are 11 interesting races to watch on Tuesday night.

US Senate: Marsha Blackburn vs Phil Bredesen

After U.S. Sen. Bob Corker's bombshell retirement announcement late last year, U.S. Rep. Marsha Blackburn and former Democratic Gov. Phil Bredesen effectively cleared the field of anyone interested in the race.

In the 13 months since Corker's decision, the Republican and Democratic nominees, respectively, have made their cases to voters.

Blackburn, who has aligned herself closely with President Donald Trump, has championed national issues ranging from her opposition to the Affordable Care Act to immigration reform while using partisan rhetoric to vie for the seat.

Bredesen has taken a more moderate, issues-based approach, while attempting to localize the race and suggest he will move away from partisan politics in favor of working on big ideas.

The race, which has drawn national interest as Republicans look to defend their 51-49 majority in the Senate, has quickly become the most expensive race in Tennessee history.

Governor: Bill Lee vs. Karl Dean

Term-limited Republican Gov. Bill Haslam is finishing out his eighth year of office, and Williamson County businessman Bill Lee and former Nashville Mayor Karl Dean are vying for his post.

Lee, a Republican seeking office for the first time, triumphed over U.S. Rep. Diane Black, R-Gallatin; state House Speaker Beth Harwell, R-Nashville; and Knoxville businessman Randy Boyd in the party's August primary.

He has framed his lack of political experience as an asset, focusing on his time running the Lee Company, a Franklin-based HVAC, plumbing and electrical business. Lee has stressed the need for more vocational training in the state, starting at the high school level.

Dean, like Bredesen, has run as a centrist Democrat touting his moderate, pro-business policies and willingness to work with Republicans. He beat out House Minority Leader Craig Fitzhugh in the Democratic primary.

Dean has made Medicaid expansion a central component of his platform, calling for the Republican-controlled legislature to take up the issue in order to extend health care coverage to hundreds of thousands of uninsured Tennesseans.

7th Congressional District: Mark Green vs. Justin Kanew

Four candidates — one Republican, one Democrat and two independents — are vying for the congressional seat left open by U.S. Rep. Marsha Blackburn.

Blackburn, a Brentwood Republican, is giving up her seat to run for the U.S. Senate.

The seat has been a Republican stronghold for eight terms. Issues in the district range from rural hospital closings to the expansion of broadband internet.

Republican state Sen. Mark Green and Democrat Justin Kanew are the leading contenders for the seat.

Green started his career in politics in 2012 when he ran for the Tennessee General Assembly. In the state Senate, he serves as Senate Commerce Committee vice chair and Senate GOP Caucus chaplain. The Republican also found himself in the national spotlight as a nominee for U.S. Army secretary.

Kanew, a 39-year-old College Grove resident, moved to Tennessee two years ago with his wife and daughter from Southern California. He is a film writer and producer and past contestant on the television show "The Amazing Race."

The two independents are Leonard Ladner and Brent Legendre.

State Senate District 31: Brian Kelsey vs. Gabby Salinas

Political newcomer Gabby Salinas, a Democrat, is seeking to defeat Brian Kelsey, the Republican incumbent.

Leaders of both major parties say population changes in the district, which covers much of East Memphis and suburban areas such as Germantown, could favor Democrats.

Republicans in the state appear to be feeling the heat as one group has spent more than $300,000 on advertising against Salinas, portraying her as a radical.

On the campaign trail, Kelsey has touted his accomplishments in office.

Salinas, a cancer survivor and scientist at St. Jude Children's Research Hospital, has sought to make Medicaid expansion a key issue in the race.

House District 13: Eddie Smith vs. Gloria Johnson

One of the closest races in the state the last two cycles will go for round three.

Smith unseated Johnson in 2014 and beat her again in 2016 by a total of approximately 300 votes out of 35,400 ballots cast. Gov. Bill Haslam ran ads across Knoxville in support of Smith last time and it was just enough.

Smith owns an event management company. Before he starting that business in 2014, he worked at a local Baptist church for 13 years. He is the vice-chair of the House Education Administration and Planning Committee and is running a campaign centered on fiscal responsibility and business friendliness.

Johnson is a retired special education teacher and former Knox County Democratic Party chair. She has campaigned on an education and access to health care. She served one term in the state legislature.

But this year’s race has a wild card. Independent candidate Zachary Houk could steal votes from either candidate and make for another interesting finish.

House District 18: Martin Daniel vs. Greg Mackay

Two Knoxville politicos face off in West Knoxville’s normally reliable Republican district.

Daniel was first elected in 2014 after he knocked of Rep. Steve Hall in the Republican primary and he easily won re-election in 2016.

He is the owner of Elevation Outdoor Advertising LLC and is a frequent critic of the University of Tennessee on several issues, including UT’s now-defunded Office of Diversity and Inclusion.

Daniel’s campaign is centered on his experiences as a small business owner, someone who understands budgets and is a problem solver.

Mackay is a real estate agent and former administrator of the Knox County Elections Commission who has campaigned on health care reform and his willingness to work across the aisle once in Nashville. He served on the local election commission before becoming administrator.

House District 33: John Ragan vs. Richard Dawson

The tech and industrial center of Oak Ridge and most of Anderson County make up House District 33, which will see a contested race between two U.S. Air Force veterans.

Republican Rep. John Ragan, a retired pilot turned business consultant, has served in Nashville since 2010 when he narrowly defeated former Democrat Rep. Jim Hackworth. Two years later he nicked Hackworth again and has had little challenge holding the seat since.

Ragan is the vice chair of the House Government Operations Committee and the vice chair that committee’s Health and General Welfare Subcommittee.

He made news in 2017 for a bill that would have put “alien” on non-U.S. citizen Tennessee driver’s licenses and other forms of identification. The bill was amended to say “visa” and was signed into law by Gov. Haslam in April.

Richard Dawson is a retired commercial pilot who flew helicopters for the Army in Vietnam before attending school on the GI Bill and serving in the Air Force for 20 years.

He isn’t new to politics as he served two terms as the chairman of the Anderson County Democratic Party and is running on a campaign of providing a living wage to workers, comprehensive health care and good schools.

House District 56: Brent Moody vs. Bob Freeman

Despite being a historically Republican district that has been represented by House Speaker Beth Harwell for 30 years, Democrats are optimistic they can turn this seat in their favor.

Businessman Bob Freeman, who is the son of wealthy Democratic donor Bill Freeman, is squaring off against Nashville surgeon Brent Moody.

The affluent district, which includes Belle Meade, Forest Hills, Oak Hills and Green Hills, showed soft support for Trump during the 2016 election; parts of Green Hills even broke for Hillary Clinton.

As such, Freeman has spent significant money to run television ads for several weeks, while Moody refers to himself as a reasonable and responsible Republican.

The race is likely one of the best opportunities for Democrats to pick up a Republican seat in the statehouse.

House District 67: Tommy Vallejos vs. Jason Hodges

Three candidates are running for House District 67, a seat being vacated by Rep. Joe Pitts, who’s running for Clarksville mayor. The district covers most of the city of Clarksville.

Democrat Jason Hodges, a Marine Corps veteran, was elected to the Montgomery County Commission in 2014. He graduated from Northeast High School and Austin Peay State University, and works as the operations manager with Clarksville-Montgomery County Schools.

Republican Tommy Vallejos is a former Montgomery County commissioner and pastor. He retired from the Army after 21 years, and has a degree from the North Tennessee Bible Institute and Seminary. He’s known for his past as a gang member who reformed into a conservative Republican.

John Dawson, the independent candidate, retired from the Army in 2007 after 20 years, and currently works as a program analyst. He has an associate’s degree in aviation technology.

House District 82: Chris Hurt vs. Andrea Bond-Johnson

Tennessee House District 82 features two newcomers, Republican Chris Hurt and Democrat Andrea Bond-Johnson.

One of them will fill the seat now held by House Minority Leader Craig Fitzhugh, who ran an unsuccessful bid for the Democratic nomination for governor.

Hurt, of Halls, is the owner of Hurt Land & Reality real estate company and a former teacher and football coach. He worked at Halls High School from 2000 to 2014.

His platform centers on removing regulations for farmers and small businesses, according to his campaign website.

Bond-Johnson is the CEO of Golden Circle Insurance Agency, a spinoff from Golden Circle Life Insurance Company, a company founded by her grandfather. She is also a licensed funeral director.

Her platform centers on the expansion of Medicaid in Tennessee, according to her campaign website.

District 82 includes Lauderdale, Crockett and Haywood Counties.

House District 96: Scott McCormick vs. Dwayne Thompson

The race for state House District 96 features a Republican Shelby County Schools board member running against a Democrat incumbent.

Scott McCormick, of East Memphis, looks to unseat Dwayne Thompson, of Cordova, in the race to represent Cordova and part of Germantown.

Thompson, a human resources professional, also served six years in the U.S. Army Reserve, according to his campaign website. He is a member of the House committees on consumer and human resources, insurance and insurance and banking.

McCormick serves as the District 5 representative on the school board. He served on the Memphis City Council from 2004 to 2008 as chairman of the Parks Committee until being elected as chairman of the council in 2007.

He also served as director of the Memphis Botanic Garden from February 2015 to May 2016.

On the school board, McCormick heads the committee tasked with the superintendent's annual evaluation.
